Black Phillipwrote a review of Shimano XT/Ultegra CN-HG701 11-Speed Chain on May 24, 2019
Familiarity: I've used it several times
This latest incarnation of the Ultegra 11-speed chain lives up to expectations. You DO need chain pliers to install the master link, as it won’t immediately (and securely) click into place by simply putting pressure on a pedal to pull the chain apart, as is the case with SRAM PowerLock connecting links.
The factory lubricant on this Ultegra chain is much thinner and silkier than the grease-like stuff usually found on new chains. Do yourself a favor and leave it on until it begins to wear off. Just wipe off any excess lube and go ride. The chain shifts beautifully with it.
